PyQt5基本布局

作者:互联网

水平布局:

 

代码:

# -*- coding: utf-8 -*-

import sys
from PyQt5.QtWidgets import *

class WinForm(QWidget):
    def __init__(self, parent = None):
        super(WinForm,self).__init__(parent)
        self.setWindowTitle('水平布局管理例子')
        hlayout = QHBoxLayout()
        hlayout.addWidget(QPushButton(str(1)))
        hlayout.addWidget(QPushButton(str(2)))
        hlayout.addWidget(QPushButton(str(3)))
        hlayout.addWidget(QPushButton(str(4)))
        hlayout.addWidget(QPushButton(str(5)))
        hlayout.addWidget(QPushButton(str(6)))
        self.setLayout(hlayout)

if __name__ == "__main__":
    app = QApplication(sys.argv)
    form = WinForm()
    form.show()
    sys.exit(app.exec_())

 竖直布局与这个差不多就把QHBoxLayout  改成 QVBoxLayout  就可以啦。

addStretch函数:

# -*- coding: utf-8 -*-
import sys
from PyQt5.QtWidgets import *

class WinForm(QWidget):
    def __init__(self, parent = None):
        super(WinForm,self).__init__(parent)
        self.setWindowTitle('伸缩量管理例子')

        btn1 = QPushButton()
        btn2 = QPushButton()
        btn3 = QPushButton()

        btn1.setText('one')
        btn2.setText('two')
        btn3.setText('three')

        hbox = QHBoxLayout()
        hbox.addStretch(2)
        hbox.addWidget(btn1)
        hbox.addStretch(2)
        hbox.addWidget(btn2)
        hbox.addStretch(2)
        hbox.addWidget(btn3)

        self.setLayout(hbox)



if __name__ == "__main__":
    app = QApplication(sys.argv)
    form = WinForm()
    form.show()
    sys.exit(app.exec_())

 QGridLayout

常用的方法: 

 

代码:

# -*- coding: utf-8 -*-

import sys
from PyQt5.QtWidgets import *


class FormW(QWidget):
    def __init__(self,parent = None):
        super(FormW,self).__init__(parent)
        self.initUI()

    def initUI(self):
        #1
        grid = QGridLayout()
        self.setLayout(grid)

        #2
        names =['Cls', 'Back', '', 'Close',
                '7', '8','9','/',
                '4','5','6','*',
                '1','2','3','-',
                '0','.','=','+']

        #3
        positions = [(i,j) for i in range(5) for j in range(4)]

        #4
        for position, name in zip(positions,names):
            if name == '':
                continue
            button = QPushButton(name)
            grid.addWidget(button,*position)

        self.move(300,150)
        self.setWindowTitle('网络布局管理例子')



if __name__ == "__main__":
    app = QApplication(sys.argv)
    form = FormW()
    form.show()
    sys.exit(app.exec_())

 基本布局就简单介绍到这里,如果想比较复杂的话,请使用他们相互的组合。这个还是非常简单的。
